TECHNICAL FIELD

The present invention relates to a flooring system including a floor panel for use in forming a graded floor or pathway and to methods of use thereof. In particular, the present invention concerns a preformed load bearing panel for use in forming a graded floor or pathway and to methods of use thereof.

BACKGROUND

Proper drainage is critical in any construction project, particularly in the building industry. Improper drainage can quickly lead to deterioration of building elements and costly repairs.

For example, modern building and construction codes generally require that any wet area (e.g., bathrooms, laundries, en-suites and the like) be constructed so that water flows to a floor waste or drainage inlet defined in the wet area floor, without ponding or pooling of water. This is typically achieved by forming a graded wet area floor that permits drainage to the floor waste.

The forming of graded wet area floors generally involves forming a recessed area known as a “step down” in a slab in the location where the wet area is intended to be located. A graded wet area floor is then manually formed atop the step down with a dry mix of concrete. The wet area is formed to fall or taper towards the floor waste defined in the step down. Once formed, the floor is allowed to dry before being typically finished with water proofing and tiling.

Likewise, outdoor entertainment areas, such as, e.g., decks, patios and the like, and outdoor pathways are also usually constructed to be graded to permit drainage of water away from the areas or pathways, again without ponding or pooling.

As with the forming of graded wet area floors, the process typically includes manually forming the area or pathway to fall or taper away from the area or pathway, generally to a side of the area or pathway farthest away from any building structure.

Problems in general with the above processes are that they are time-consuming, tedious and labour-intensive, particularly the defining of a step down in a slab, the manual forming of the graded area, wet area or pathway and the time spent waiting for the area or pathway to set.

SUMMARY OF INVENTION

Embodiments of the present invention provide a preformed load bearing floor panel and methods of use thereof, which may minimise or overcome at least one of the problems mentioned above, or which may provide the public with a useful or commercial choice.

According to a first aspect of the present invention, there is provided a wet area flooring system for forming a graded and waterproofed wet area floor in a room, said system comprising:

a plurality of preformed load bearing floor panels configured to be arranged on a support surface around at least one floor waste in a side edge-to-side edge arrangement so as to form a graded wet area floor in which a gradient of each panel directs water or any other liquid in a direction towards the at least one floor waste, wherein each said panel comprises:

-   -   two opposed surfaces comprising a lower surface and an opposed         upper surface, said opposed upper surface configured to have         tiling applied thereon, said opposed surfaces being         interconnected by opposed end edges and opposed side edges, each         said panel tapering in thickness from a first of said opposed         end edges to a second of said opposed end edges with a gradient         ranging from about 0.1% to about 2.0% to thereby direct said         water or any other liquid atop the panel from the first of said         opposed end edges to the second of said opposed end edges; and

one or more skirting boards configured to be arranged around an outer edge of the room at a junction between an adjacent wall and said first said opposed end edge of an adjacent said panel, wherein each skirting board comprises:

-   -   two opposed surfaces comprising a wall abutting surface and an         outer surface, said opposed surfaces being interconnected by         opposed end edges and opposed side edges, each said skirting         board extending longitudinally between said opposed end edges,

wherein the plurality of the preformed load bearing floor panels and the one or more skirting boards are each formed from a waterproof material, and

wherein when arranged said plurality of preformed load bearing floor panels and said one or more skirting boards are waterproof bonded to form the waterproofed wet area floor in the room.

According to a second aspect of the present invention, there is provided a preformed load bearing floor panel for use in forming a graded floor, wet area or pathway, said panel having two opposed surfaces including a lower surface and an opposed upper surface, said opposed surfaces interconnected by opposing edges including opposed end edges and opposed side edges, said panel tapering in thickness from a first of said opposed end edges to a second of said opposed end edges with a gradient ranging from about 0.1% to about 2.0% permitting drainage of water or any other liquid atop the panel from the first of said opposed end edges to the second of said opposed end edges, wherein said panel is configured to be arranged next to at least one further like panel in a side edge to side edge arrangement to form the graded floor or pathway.

According to a third aspect of the present invention, there is provided a preformed load bearing panel for use in forming graded decking, said panel having two opposed surfaces including an upper surface upon which decking is fastened and an opposed lower surface configured to be fastened to a support surface, said opposed surfaces interconnected by opposing edges including opposed end edges and opposed side edges, said panel tapering in thickness from a first of said opposed end edges to a second of said opposed end edges with a gradient ranging from about 0.1% to about 2.0% permitting drainage of water or any other liquid atop the panel from the first of said opposed end edges to the second of said opposed end edges, wherein said panel is configured to be arranged next to at least one further like panel in a side edge to side edge arrangement to form the graded decking.

Advantageously, the flooring system and panel of the present invention enables a graded wet area floor to be readily formed while being fully waterproof. The panel of the present invention also enables a graded floor, pathway, wet area or decking to be readily formed. The above is achieved by simply laying, applying or fastening one or more of the panels atop a support surface in a side edge to side edge arrangement. The floor panels are particularly advantageous in quickly forming graded wet area floors as they obviate the need for a step down to be defined in the slab and the need to manually form a graded floor atop the step down with a dry mix of concrete. Moreover, being preformed load bearing panels, the panels of the present invention obviate the time required to apply formwork, pour concrete and wait for the concrete to cure. As such, a graded wet area floor can now be quickly formed with the panels by removing any delay in waterproofing and tiling the intended wet area while waiting for a manually formed graded floor to set, for example. Indeed, in some embodiments, the present invention obviates the need to waterproof.

As used herein, the term “floor waste” refers to a drain inlet defined in a floor surface. In some embodiments, a floor surface or support surface may include more than one floor waste. For example, the floor or support surface may include a first floor waste for a shower and a second floor waste for a remainder of a room.

As used herein, the term “step down” refers to a recessed area defined in a slab, usually in a location where a wet area is intended to be located. For example, step downs are typically defined in a slab where a bathroom, laundry or en-suite is intended to be located.

As used herein, the term “fall” refers to the gradient of a floor surface or part or portion thereof. Typically, the fall is a negative gradient that is directed in a desired location, such as, e.g., toward a floor waste, a drain or a desired edge.

As used herein, the term “load bearing” refers to the capacity of the preformed floor panel of the present invention to carry or support a load. Generally, the preformed floor panel will in use have a capacity to carry or support both a dead load and a live load. The dead load may include tiling or decking affixed atop the floor panel. The live load may include the weight of furnishings, people and other articles supported atop the floor panel but not permanently affixed to the floor panel.

The floor panel may be of any suitable size, shape and construction and may be formed from any suitable material or materials.

Generally, the floor panel may have a polygonal shape suitable for tiling. Typically, the panel may be substantially rectangular, triangular, hexagonal, heptagonal, octagonal or oblong-shaped, or any variation or combination thereof. Preferably, the panel may be rectangular or square-shaped.

As indicated above, the panel has two opposed surfaces including a lower surface and an opposed upper surface. The opposed surfaces are interconnected by opposing edges including opposed end edges and opposed side edges with the panel tapering in thickness from a first said end edge to an opposed second said end edge with a gradient ranging from about 0.1% to about 2.0% permitting drainage of water or any other liquid atop the panel from the first said end edge to the second of said end edge.

The floor panel may be of any desired length and/or width.

For example, the panel may have a length and/or width of at least 300 mm, at least 350 mm, at least 400 mm, at least 450 mm, at least 500 mm, at least 550 mm, at least 600 mm, at least 650 mm, at least 700 mm, at least 750 mm, at least 800 mm, at least 850 mm, at least 900 mm, at least 950 mm, at least 1,000 mm, at least 1,050 mm, at least 1,100 mm, at least 1,150 mm, at least 1,200 mm, at least 1,250 mm, at least 1,300 mm, at least 1,350 mm, at least 1,400 mm, at least 1,450 mm, at least 1,500 mm, at least 1,550 mm, at least 1,600 mm, at least 1,650 mm, at least 1,700 mm, at least 1,750 mm, at least 1,800 mm, at least 1,850 mm, at least 1,900 mm, at least 1,950 mm, at least 2,000 mm, at least 2,050 mm, at least 2,100 mm, at least 2,150 mm, at least 2,200 mm, at least 2,250 mm, at least 2,300 mm, at least 2,350 mm, at least 2,400 mm, at least 2,450 mm, at least 2,500 mm, at least 2,550 mm, at least 2,600 mm, at least 2,650 mm, at least 2,700 mm, at least 2,750 mm, at least 2,800 mm, at least 2,850 mm, at least 2,900 mm, at least 2,950 mm, at least 3,000 mm, at least 3,050 mm, at least 3,100 mm, at least 3,150 mm, at least 3,200 mm, at least 3,250 mm, at least 3,250 mm, at least 3,300 mm, at least 3,350 mm, at least 3,400 mm, at least 3,450 mm, at least 3,500 mm, at least 3,550 mm, at least 3,600 mm, at least 3,650 mm, at least 3,700 mm, at least 3,750 mm, at least 3,800 mm, at least 3,850 mm, 3,900 mm, at least 3,950 mm or at least 4,000 mm.

In some embodiments, the floor panel may be provided in one or more standard lengths and/or widths. For example, the floor panel may be provided in standard lengths of 1,800 mm, 2,100 mm, 2,400 mm, 2,700 mm, 3,000 mm or 4,000 mm. Likewise, the floor panel may be provided in standard widths of 600 mm, 900 mm, 1,200 mm or 1,350 mm.

In other embodiments, the floor panels may be formed to custom lengths and/or widths.

Likewise, the floor panel may be of any suitable thickness tapering from the first said end edge to the opposed second said end edge with a gradient of at least 0.1%.

For example, the floor panel may have a maximum thickness (as measured at the first said end edge between the opposed surfaces) of at least 5 mm, at least 10 mm, at least 15 mm, at least 20 mm, at least 25 mm, at least 30 mm, at least 35 mm, at least 40 mm, at least 45 mm, at least 50 mm, at least 55 mm, at least 60 mm, at least 65 mm, at least 70 mm, at least 75 mm, at least 80 mm, at least 85 mm, at least 90 mm, at least 95 mm or even at least 100 mm. Typically, the panel may have a maximum thickness of about 10 mm to about 30 mm, preferably about 10 mm.

Typically, the panel may have any suitable gradient that permits the drainage of water atop the panel from the first said end edge to the second said end edge.

For example, in some embodiments, the floor panel may have a gradient of at least 0.2%, at least 0.3%, at least 0.4%, at least 0.5%, at least 0.6%, at least 0.7%, at least 0.8%, at least 0.9%, at least 1.0%, at least 1.1%, at least 1.2%, at least 1.3%, at least 1.4%, at least 1.5%, at least 1.6%, at least 1.7%, at least 1.8%, at least 1.9% or even at least 2.0%.

Generally, the floor panel may taper in thickness from the first said end edge to the opposed second said end edge with a gradient of about 0.1% to 0.5%, preferably about 0.2% to about 0.45%.

Preferably, the gradient may be a negative gradient extending from the first said end edge to the second said end edge.

In some embodiments, the panel may taper in thickness from the first said end edge to the second opposed said end edge with a constant gradient. In other embodiments, the panel may taper in thickness from the first said end edge to the second opposed said end edge with a varying gradient, such as, e.g., an increasing or decreasing gradient.

In some embodiments, the panel may taper in thickness such that the second said end edge forms a single edge (i.e., the opposed surfaces meet). In other embodiments, the second said end edge may form an edge wall extending between the opposed surfaces.

Generally, the floor panel is formed from a durable and load bearing material. For example, the floor panel may be formed from metal, plastic, rubber, glass, fibre, concrete, stone and/or wood material and/or materials, preferably concrete material. In some embodiments, the floor panel may be formed from a mixture of magnesium oxide, at least one binding or filling agent (e.g., carbon fibre, cellulosic fibre, perlite and/or fly ash) and at least one reinforcing mesh positioned between the opposed surfaces.

In some embodiments, the floor panel may be formed from concrete or a cement-polymer composite material. The panel may or may not include at least one reinforcing mesh located between the opposed surfaces.

In other embodiments, the floor panel may be formed from a plastic material or a plastic composite material. For example, the panel may be formed from polyvinyl chloride (“PVC”). In such embodiments, the floor panel may preferably be waterproof. Advantageously, the use of such panels obviates the need for subsequent waterproofing treatments. If formed of plastic, the floor panel may be formed as a plastic extrusion.

In some embodiments, the floor panel may be formed from a plastic material or composite comprising a heat resistant or thermally stable plastic. Advantageously, by having heat resistant or thermally stable properties, the plastic floor panels may be safely used with an under tile heating system.

In some embodiments, at least one of the opposed surfaces of the panel may be textured to at least partially assist in fastening material to the panel, such as, e.g., water proofing, tiling, decking or the like. Preferably both of the opposed surfaces may be textured.

In some embodiments, the floor panel or at least part of the floor panel may be treated with a damp-proof or waterproofing coating, preferably pre-treated.

In some embodiments, at least one of the opposed surfaces of the panel, preferably the upper surface may include one or more markings to assist in arranging materials atop the panel. For example, in one such embodiment, the upper surface of the floor panel may include markings to assist in the placement of tiles atop the panel. In another such embodiment, the upper surface may include markings to assist in the placement and/or spacing of deck boards atop the panel.

Generally, the panel may be laid or applied atop and/or fastened to a support surface with one or more other like panels to form a graded pathway, floor, wet area or decking area. The panels may be arranged in any suitable way.

The support surface may be any suitable surface atop of which the panel may be laid and/or fastened. Typically, the support surface may be a portion or part of a slab, a step down area defined in slab, two or more horizontal support beams, such as, e.g., floor joists, or one or more other underlying floor panels (e.g., Scion™ Secura™ interior flooring panels or HardiePanel™ compressed sheet) supported atop one or more horizontal support beams. In embodiments in which the support surface comprises two or more horizontal support beams, a panel or sheet may be laid atop to cover any gaps between the horizontal support beams prior to the panels being laid and/or fastened. The panel or sheet of sheet may comprise a plywood or block board panel or sheet, for example.

Typically, each panel may be laid or applied atop or fastened to the support surface in a side edge-to-side edge arrangement with other like panels to form a graded surface. In some embodiments, the panels may need to be trimmed and/or mitred along one or both side edges to be suitably arranged. The side edges of adjacently positioned panels may or may not be joined together.

If joined together, the panels may be joined together by any suitable means.

For example, in some embodiments, the side edges may be joined together by one or more fasteners. The one or more fasteners may include one or more mechanical fasteners (such as, e.g., threaded fasteners) and/or one or more chemical fasteners (such as, e.g., a wet adhesive, a dry adhesive or a double-sided adhesive tape).

In other embodiments, each side edge of adjacently positioned panels may be connected together by a connecting mechanism or a part of a connecting mechanism. For example, a portion of a side edge of a first panel may mate with or engage with a portion of a side edge of a second panel.

The connecting mechanism may include mateable male and female portions that couple together, including interference fit (snap-fit) connections, for example. The connecting mechanism may include a male formation associated with a side edge of a first panel configured to be inserted into or coupled with a female formation associated with a female formation associated with a side edge of the second panel.

In some embodiments, a sealing member or sealing agent may be at least partially applied along a side edge of a panel to be joined with a side edge of an adjacently positioned panel.

Any suitable sealing member or agent may be used that may preferably provide a substantially water-tight seal between side edges of adjacently positioned panels.

In some embodiments, the sealing member may be formed from any suitable material or materials, such as, e.g., closed foam, rubber, expanding resin or a like material suitably adapted to form a seal.

In other embodiments, the sealing agent may include a mastic sealant or any other like sealant suitably adapted to form a seal.

In yet other embodiments, the panels may be joined together by waterproof bonding. The waterproof bonding may include any suitable bonding that is able to achieve a water-tight seal or join between side edges of adjacently positioned panels.

In embodiments in which the panels are formed from a plastic or plastic composite material, the waterproof bonding may include plastic welding, preferably hot gas welding. For example, a hot air welder may be used to soften both edges to be joined and a plastic filler rod may be used to apply at least one weld bead along the edges to be joined. Advantageously, the use of plastic welding with plastic panels provides an entirely waterproof solution.

The panels may preferably be arranged or orientated on the support surface such that the fall of each panel is directed in a desired direction.

For example, when forming a graded wet area floor having a floor waste, the panels may typically be arranged or orientated on the support surface such that the gradient or taper of each panel directs water or any other liquid towards the floor waste.

For example, when forming a graded pathway, decking area or floor without a floor waste, the panels may typically be arranged or orientated in a same or similar orientation on the support surface in a side edge-to-side arrangement such that the gradient or taper of each panel directs water or any other liquid in a desired direction, usually away from any adjacent structure. For example, when forming a graded deck, each panel may be orientated to direct water away from an adjacent structure.

The panels may be fastened to the support surface by any suitable means. Typically, each panel may be fastened to the support surface by one or more fasteners, such as, e.g., one or more mechanical fasteners and/or one or more chemical fasteners as described above.

Preferably, the panels may be fastened to the support surface with a chemical adhesive, such as, e.g., a cement-based tile adhesive.

In some embodiments, the panel may be trimmed or shaped to fit around an adjacent structure. For example, the second opposed said end edge of a panel may be trimmed or shaped to snugly fit about a floor waste.

As indicated above, the system of the first aspect further includes one or more skirting boards configured to be arranged around an outer edge of a room at a junction between an adjacent wall and a first opposed end edge of a floor panel for forming a waterproofed wet area floor.

The skirting board may be of any suitable size, shape and construction and may be formed from any suitable waterproof material or materials.

Typically, the skirting board may have a polygonal shape, preferably a rectangular shape for being arranged along the junction. Preferably, each skirting board may have an elongate shape.

As indicated, each skirting board has two opposed surfaces extending substantially parallel to one another and interconnected by opposing edges. The two opposed surfaces include a wall abutting surface configured to be attached or fastened to at least a portion of the wall and an opposed outer surface. The opposing edges include opposed end edges and opposed side edges. The skirting board may preferably extend longitudinally between the opposed end edges.

In some embodiments, the outer surface of each skirting board may be configured to have tiling applied thereon.

In some embodiments, at least the outer surface of the board may be textured to at least partially assist in tiling.

In some embodiments, at least the outer surface of the board may include one or more markings to assist in applying tiles thereon. The markings may preferably assist in the placement of the tiles.

Each skirting board may have a maximum thickness (as measured between the opposed surfaces) of about 1 mm, about 2 mm, about 3 mm, about 4 mm, about 5 mm, about 6 mm, about 7 mm, about 8 mm, about 9 mm, or about 10 mm or more.

Each skirting board may typically have a width (as measured between the opposed side edges) of about 20 mm, about 25 mm, about 30 mm, about 35 mm, about 40 mm, about 45 mm, about 50 mm, about 55 mm, about 60 mm, about 65 mm, about 70 mm, about 75 mm, about 80 mm, about 85 mm, about 90 mm, about 95 mm, about 100 mm, about 105 mm, about 110 mm, about 115 mm, about 120 mm, about 125 mm, about 130 mm, about 135 mm, about 140 mm, about 145 mm, or about 150 mm or more.

The skirting board may be formed from a durable and waterproof material. For example, the board may be formed from metal, plastic, rubber, glass, fibre and/or wood material and/or materials. In some embodiments, the skirting board may be formed from a plastic material or a plastic composite material, such as, e.g., polyvinyl chloride (“PVC”).

Preferably the skirting boards may be formed as plastic extrusions to any desired length for extending along a junction.

Each skirting board may be fastened to at least a lower portion of the wall adjacent the junction by any suitable means.

For example, in some embodiments, each skirting board may be fastened to the lower portion of the wall by one or more fasteners. The one or more fasteners may include one or more mechanical fasteners (such as, e.g., threaded fasteners) and/or one or more chemical fasteners (such as, e.g., a wet adhesive, a dry adhesive or a double-sided adhesive tape).

In preferred embodiments, the wall abutting surface of each skirting board may be adhesively bonded to the lower portion of the wall.

In some embodiments, the system may further include one or more shower wall panels configured to be arranged at a junction between a wall and a first opposed end edge of at least one floor panel at a location in which a shower is to be located in the wet area floor. A person skilled in the art will appreciate that the one or more shower wall panels may also be arranged at a junction between a wall and a first opposed end edge of at least one floor panel at a location in which a bath is to be located.

Each shower wall panel may be of any suitable size, shape and construction and may be formed from any suitable waterproof material or materials.

Generally, the shower wall panel, like the skirting board, may have a polygonal shape, preferably a rectangular or square shape for being arranged along the junction in a shower space. Typically, shower wall panel may be sized and shaped to at least partially span the width and height of a shower cavity wall, preferably entirely span.

Each shower wall panel may have two opposed surfaces extending substantially parallel to one another and interconnected by opposing edges.

The two opposed surfaces may include a wall abutting surface configured to be attached or fastened to at least a lower portion of the wall and an opposed outer surface.

The opposing edges may include opposed end edges and opposed side edges. In some embodiments, the shower wall pane may extend longitudinally in a substantially vertical direction between the opposed end edges.

In some embodiments, the outer surface of each shower wall panel may be configured to have tiling applied thereon.

In some embodiments, at least the outer surface of the panel may be textured to at least partially assist in tiling.

In some embodiments, at least the outer surface of the panel may include one or more markings to assist in applying tiles thereon. The markings may preferably assist in the placement of the tiles.

Each shower wall panel may have a maximum thickness (as measured between the opposed surfaces) of about 1 mm, about 2 mm, about 3 mm, about 4 mm, about 5 mm, about 6 mm, about 7 mm, about 8 mm, about 9 mm, or about 10 mm or more.

Again like the skirting board, the shower wall panel may be formed from a durable and waterproof material. For example, the panel may be formed from metal, plastic, rubber, glass, fibre and/or wood material and/or materials. In some embodiments, the panel may be formed from a plastic material or a plastic composite material, such as, e.g., polyvinyl chloride (“PVC”).

Preferably the shower wall panel may be formed as a plastic extrusion to a desired length and/or width for extending along a junction and at least a lower portion of the wall. Typically, each shower wall panel may be trimmed and/or mitred along one or more edges to suitably fit.

In some embodiments, two or more shower wall panels may be arranged side-by-side to fit a corner of a shower space. The two or more shower wall panels may preferably be waterproof bonded together as described above, preferably in a side-to-side edge arrangement.

In some embodiments, the shower wall panels may also be waterproof bonded to adjacently positioned or arranged floor panels to advantageously provide a waterproof shower space in the wet area floor.

In other embodiments, the shower wall panels may be waterproof bonded to an adjacently positioned preformed shower tray, again to advantageously provide a waterproof shower space in the wet area floor.

Each shower wall panel may be fastened to at least a lower portion of the wall adjacent the junction by any suitable means.

For example, in some embodiments, each shower wall panel may be fastened to the lower portion of the wall by one or more fasteners. The one or more fasteners may include one or more mechanical fasteners (such as, e.g., threaded fasteners) and/or one or more chemical fasteners (such as, e.g., a wet adhesive, a dry adhesive or a double-sided adhesive tape).

FIG. 5 shows a wet area flooring system (500) according to an embodiment of the present invention for forming a graded and waterproof wet area surface (220) floor in a room (900).

The system (500) includes a plurality of preformed load bearing floor panels (100) configured to be arranged on a support surface around a floor waste (280) in a side edge (105) to side edge (105) arrangement so as to form a graded wet area surface (220) in the bathroom (230) of the room (900). A preformed shower tray (920) having a gradient to an associated floor waste (280 is arranged in the shower (260). The gradient of each floor panel (100) and shower tray (920) directs water or any other liquid in a direction towards an associated floor waste (280).

As with the embodiment shown in FIG. 1, each floor panel (100) includes an upper surface (102), an opposed lower surface (104), opposed side edges (105) and opposed end edges, including a first end edge (106) and an opposed second end edge (108). The floor panel (100) tapers in thickness from the first end edge (106) to the second end edge (108) with a gradient of at least 0.1%. The gradient is a negative gradient configured to direct water or any other liquid towards the second end edge (108), which is configured to be located adjacent a floor waste (280).

The system (500) includes one or more skirting boards (510) configured to be arranged at least partway around an outer edge of the room (900) at a junction between an adjacent wall (910) and the first end edges (106) of an adjacently arranged floor panels (100).

Each skirting board (510) includes a wall abutting surface (512), an opposed outer surface (514), opposed end edges (516) and opposed longitudinal side edges (518).

The system (500) further includes one or more shower wall panels (520) configured to be arranged at the junction between an adjacent wall (910) and a side edge (922) of the shower tray (920) at a location in which a shower (260) is to be located in the room (900).

Like with the skirting boards (510), each shower wall panel (520) is of a rectangular shape and includes a wall abutting surface (522), an opposed outer surface (524), opposed end edges (526) and opposed longitudinal side edges (528).

In this embodiment, the preformed load bearing floor panels (100), the skirting boards (510) and the shower wall panels (520) are all formed from the waterproof material polyvinyl chloride (“PVC”) as is the shower tray (920). The floor panels (100), the skirting boards (510), the shower wall panels (520) and the shower tray (920) are waterproof bonded to one another by plastic welding to form the waterproofed wet area surface (220) in the room (900). The load bearing floor panels (100), the skirting boards (510) and the shower wall panels (520) are each formed as plastic extrusions.

In this embodiment, each floor panel (100) has a thickness of about 10 mm at the first end edge (106) and a thickness at the second end edge (108) of about 2 mm. Thus, the panel (100) has a negative gradient of 0.88%, 0.66%, 0.59%, 0.44%, 0.38% and 0.33% at the respective standard lengths of 900 mm, 1,200 mm, 1,350 mm, 1,800 mm, 2,100 mm, 2,400 mm, 2,700 mm, 3,000 mm and 4,000 mm.

Each of the upper surface (102) of the floor panels (100) and the outer surfaces (514, 524) of the skirting boards (510) and the shower wall panels (520) are configured to have tiling applied thereon.

The floor panels (100) are fastened to an underlying support surface with a chemical adhesive. Likewise, the wall abutting surfaces (512, 522) of the skirting boards (510) and the shower wall panels (520) are adhesively bonded to a lower portion of the wall (910) with a chemical adhesive.

As indicated, the floor panels (100), the skirting boards (510) and the shower wall panels (520) are waterproof bonded to one another by plastic welding to form the waterproofed wet area surface (220) in the room (900). Specifically, the abutting edges (105, 106, 108) of the floor panels (100) are welded together as well to adjacent objects, such as, e.g., the floor wastes (280), the shower tray (920), a skirting board (510) and/or shower wall panel (520).

Generally, abutting side and end edges (516, 518) of the skirting boards (510) are welded to adjacent objects, such as, e.g., adjacently positioned floor panels (100), skirting boards (510), the shower tray (920) and/or the shower wall panels (520).

Further, abutting side edges and end edges (526, 528) of shower wall panels (520) are welded to adjacent objects, such as, e.g., adjacently positioned floor panels (100), skirting boards (510), the shower tray (920) and/or shower wall panels (520).

In use, each floor panel (100), board (510) and wall panel (520) is trimmed, mitred and/or shaped, prior to being arranged and fastened in place, to fit around, and to, adjacent structures.

A method of forming a graded and waterproofed wet area floor surface (220) using the system (500) is now described in detail.

The method includes an initial step of preparing the support surface by cleaning the underlying support surface where the wet area is intended to be located.

At least four of the floor panels (100) are then arranged around each floor waste (280) defined in the support surface (210) where an intended wet area is to be located. The panels (100) are arranged in a side edge (105) to side edge (105) arrangement and orientated such that the first end edge (106) of each panel (100) is located near or against an outer perimeter of the intended wet area and the opposed second end edge (108) is located near or against the floor waste (280).

The edges (105, 106, 108) of each panel (100) are mitred, trimmed and/or shaped to enable the panels (100) to snugly fit side edge (106) to side edge (106) about the floor wastes (280) and other adjacent structures.

Each floor panel (100) is then fastened to the underlying support surface with a chemical adhesive, such as, e.g., a cement-based tile adhesive.

The preformed shower tray (920) is fastened in place to the underlying support surface with chemical adhesive, such as, e.g., a cement-based tile adhesive, about its associated floor waste (280).

At least two shower wall panels (520) are then arranged side edge (528) to side edge (528) at a junction between a wall (910) and an edge (922) of the shower tray (920) at a location in which a shower (260) is to be located. Each shower wall panel (520) is fastened to the wall (910) with a chemical adhesive, such as, e.g., a cement-based tile adhesive.

Once the shower wall panels (520) are arranged and fastened in place, skirting boards (510) are then arranged around outer edges of the room (900) at the junction between the wall (910) and first end edges (106) of adjacently positioned floor panels (100). Each skirting board (510) extends longitudinally along the junction and is fastened to the wall (910) with a chemical adhesive, such as, e.g., a cement-based tile adhesive.

Once the floor panels (100), the shower tray (920), the shower wall panels (520) and skirting boards (510) are arranged and fastened in place, the respective and abutting edges (105, 106, 108, 922, 516, 518, 526, 528) are waterproof bonded to one another and adjacent structures such as the floor wastes (280). The edges (105, 106, 108, 922, 516, 518, 526, 528) are waterproof bonded by plastic welding to provide the graded and waterproofed wet area floor surface (220).
